Help Battery all the sudden draining rather quickly?

[italygrl1]

I have everything on my phone set so that i have to sync it manually.I have a task killer that kills apps running everytime my screen goes off and i have had that since i got the phone and with the same settings...But as of lately it seems my battery is draining awfully quick like half a day its lasting and im constantly plugging it into the charger? My phone was fully charged and i read a book for about 1.5-2 hrs on it and the battery already dropped 2 notches..I already checked all the tips for saving battery power and im already doing them all..Could it just be a bad battery and maybe i should have it looked at or something?

There's your problem. Task killers are NOT needed with android, they only make things worse. The android os is VERY capable of managing it's own memory. Every time you kill those tasks, it will just open them back up again, thus using more battery then if you were to just leave it alone.

Also, have you tried a battery pull lately? that will usually clear up any bugs. A hard reset (factory reset) will also help a lot too if you have the time.
